Meta's Muse Hits 10M US Downloads in 40 Days

Meta's Muse AI agent achieved 10 million US downloads in 40 days.

Insta's take

"Meta's Muse just crushed it, hitting 10M US downloads fast. This AI agent is a serious player, leaving rivals in the dust with killer retention."

Meta's AI companion, Muse, has reached 10 million US downloads within 40 days of its launch. This milestone places Muse among only 11 other apps to achieve such rapid adoption. New data indicates Muse is also retaining users at higher rates compared to its AI rivals.

Specifically, Muse recorded 10.9 million downloads since its September debut, with 10.2 million in the United States. Its 7-day retention rate in the U.S. was 30%, and its 14-day retention rate was 23%. In comparison, rivals like ChatGPT, Claude, and Grok saw average 7-day retention rates of 19% and 14-day rates of 16%. Muse also reached 2.5 million daily active users on October 16, marking a 15% week-over-week increase. Globally, ChatGPT had around 15 million downloads in its first 40 days, benefiting from wider availability, while Muse is currently limited to the U.S. and Canada.

This rapid adoption and strong retention highlight Muse's early success in the competitive AI agent market. Meta's strategy of marketing Muse across its family of apps and significant advertising investment, with 39% of its total ad spend allocated to Muse in October, appears to be driving its growth and user engagement.

Why Insta thinks this matters

This rapid user acquisition and strong retention for Muse demonstrate Meta's ability to leverage its ecosystem for new product launches. Business owners and executives should note the effectiveness of cross-platform marketing and sustained advertising investment in achieving significant market penetration for new AI tools.
